I ordered 2 belts and buckles. I really like how I can inter-change the belts and buckles. I was sceptical about how the belt worked. I thought it might slide open if I pulled on it hard enough, but whatever patented design the have for it, it really does stay tight all day long. I've been using both of mine now 5-6 days a week for 3 weeks and it really is an amazing belt. I like the fact that there are no holes to try fit into and that the belt tightens to whatever you want on any day, this means it's always comfortable. Only down side is shipping it to the U.k. and having to pay customs taxes. It seems so heavy duty, they will last for years so it's worth it.
